Hi,
the whole series is trying to address issues we have on platforms where usb
and ufs init are not done before efi initialization. This is happening on
platforms where A/B update is enabled. FWU code is called early and do EFI
initialization before usb and ufs started that's why they are not visible.
We are workarounding it by starting usb/ufs from board file but this should
be more generic approach.
Thanks,
Michal
